XcmsSetWhitePoint(3)						  XLIB FUNCTIONS					      XcmsSetWhitePoint(3)

NAME
       XcmsSetWhitePoint, XcmsSetWhiteAdjustProc - modifying CCC attributes

SYNTAX
       Status XcmsSetWhitePoint(XcmsCCC ccc, XcmsColor *color);

       XcmsWhiteAdjustProc XcmsSetWhiteAdjustProc(XcmsCCC ccc, XcmsWhiteAdjustProc white_adjust_proc, XPointer client_data);

ARGUMENTS
       ccc	 Specifies the CCC.

       client_data
		 Specifies client data for the white point adjustment procedure or NULL.

       color	 Specifies the new Client White Point.

       white_adjust_proc
		 Specifies the white point adjustment procedure.

DESCRIPTION
       The XcmsSetWhitePoint function changes the Client White Point in the specified CCC.  Note that the pixel member is ignored and that the
       color specification is left unchanged upon return.  The format for the new white point must be XcmsCIEXYZFormat, XcmsCIEuvYFormat, Xcm-
       sCIExyYFormat, or XcmsUndefinedFormat.  If the color argument is NULL, this function sets the format component of the Client White Point
       specification to XcmsUndefinedFormat, indicating that the Client White Point is assumed to be the same as the Screen White Point.

       This function returns nonzero status if the format for the new white point is valid; otherwise, it returns zero.

       The XcmsSetWhiteAdjustProc function first sets the white point adjustment procedure and client data in the specified CCC with the newly
       specified procedure and client data and then returns the old procedure.
